Citrus Clonal Protection Program

The California Citrus Clonal Protection Program (CCPP) is part of the Department of Plant Pathology at the University of California at Riverside and is a cooperative program with the citrus growers of California, represented by the Citrus Research Board, the California Department of Food and Agriculture and the United States Department of Agriculture. This program serves both researchers and growers by providing a safe mechanism for the introduction of citrus varieties from around the world and then maintains these varieties in a protected, disease tested collection of important fruit and rootstock varieties that serve as as a primary source of propagating materials for California.
